Wielokryterialny, nieliniowy model wielkości zamówienia materiałów dla kopalni węgla kamiennego

In the work there is a multi-criteria model of order size of materials used in production presented. It was assumed that the consumption size of each material is a random variable of known probability distribution. In the model with the purchase cost of materials ordered limited there were three criteria: order size, probability of lack of materials in the production process, deviations of order size from the consumption size in the past periods. It was shown on an example how to use the model for determining the order sizes for polyurethane adhesive and wood in one of the hard-coal mines.
